Juss) and commercial neem based formulations using HPTLC and extended length packed-columns SFC method. Chromatographia 62 (3-4), 183-195 (2005). Two chromatographic techniques are described for the separation and quantitative determination of azadirachtin A and B, salannin, and nimbin present in the crude extract of neem seed kernels and commercial neem based formulations. HPTLC separation of markers on silica gel with ethyl acetate - benzene 7:3. Visualization under UV 254 nm. The other technique was based on extended length packed column supercritical fluid chromatographic (PC-SFC) separation of the markers. Validation of both methods in terms of precision, robustness, recovery, limits of detection and quantitation. The analysis of variance (ANOVA) and Student’s t-test were applied to correlate the results of quantitative determination of markers by means of HPTLC and PC-SFC method.
